Process analysisWhat we did well What we will change to next

time

We had a leader and a coordinator which had the overview of the project

More concentration at the meetings.

We worked 9-16 every day More concentration at group work at lectures

We had our morning meetings, so we new what has been done and what to do.

Make it a common responsibility that we keep concentration, so it is not only the responsibility of the group coordinator.

Good communication with the supervisors

Have more respect for the agenda manager at the meetings

Our good internal communication and knowledge sharing in the group.
